Experimental: Zometa neoadjuvant HER2 breast cancer
Zo-Nantax arm - Neoadjuvant chemotherapy with association of zoledronic acid and standard treatment with anthracycline followed taxane plus trastuzumab in locally advanced breast cancer HER2 positive HR positive/negative.
Drug:Cyclophosphamide Drug:Adriamycin Drug:Docetaxel Drug:Trastuzumab Drug:Zolendronic acid
Drug: AC Adriamycin 60mg/m2 IV plus cyclophosphamide 600mg/m2 every 21 days for 4 cycles
Docetaxel 100 mg/m2 every 21 days for 4 cycles.
Trastuzumab 8mg/kg [loading dose] once then 6mg/kg IV every 21 days for 3 cycles plus docetaxel.
Drug: zolendronic acid
Zolendronic acid 4mg IV every 21 days for 8 cycles combine with chemotherapy
This trial combines zolendronic acid with anthracycline followed taxane plus trastuzumab for neoadjuvant treatment of HER 2 positive stage II/III breast cancer.
Zoledronic acid (ZOL) has activity of anti-bone resorption and shows diverse anti-tumor effects in vitro. Some chemical and biological characteristics of ZOL indicate potential for inhibition of tumor growth in pre clinical studies
The primary objective of the study is to evaluate the residual cancer burden (RCB) with the addition of zolendronic acid to standard neoadjuvant therapy. RCB is calculated as a continuous index combining pathologic measurements of primary tumor (size and cellularity) and nodal metastases (number and size). RCB index is a significant predictor of distant relapse-free survival, and can be used to define categories of near-complete response and chemotherapy resistance after neoadjuvant chemotherapy compared with currently used risk factors. Additionally, the study will collect tissue biopsies and blood before and after treatment in order to correlate clinical outcomes with gene expression and radiologic data to predictive response.
